Funny story, there actually was a killer who murdered his girlfriend because she was pregnant and didn’t want an abortion.
In order to cover for this, he found out exactly how long it’d take to get to her house and back, recorded him playing GTA for that long.
He was found out because cameras on the street found him walking near her house, during the “live” event.
There were also bugs in the stream where the message “Time to die” showed up (in the context of an “ad” for a James Bond film), which were just his little way of bragging about his crime, like he was the Riddler or something.
He did too good a job with his timing, because the “glitch” happened pretty much exactly at the time of death.
I’ve seen enough of these “Perfect Murder Fails” go wrong, and it’s usually people who think they’re more clever than they really are pretty much giving all the evidence to the police.
I know of another where a film maker rented an old house, made it look like a stereotypical serial killer’s lair, filmed part of a low budget horror movie on it, and then killed a guy there.
Lemme lay down some flash non-fiction written in first person to tell you how that went
“See, it looks like a murder happened here, but the brilliant part is: It’s a set for a movie that I can prove I’ve been making! Meaning I can just not clean up after my own killing and hide in plain sight! Aaaaaand they’re testing the fake blood I used because it doesn’t look or smell anything like costume blood… And I left my manifesto cleverly disguised as my script in the car that they can now search because the blood tested positive for being real blood, meaning probable cause. I’ll just say it’s my own blood and I wanted it to be realistic! That can salvage this! Oh right tests like that also kinda tell you who’s blood it is, meaning they know it’s the victms… and my “script” describes the victim’s wounds so perfectly it can’t be coincidence… Wow, I’m fucked.”
My constant paranoia about getting in trouble for shit I didn’t do is why I don’t do crime.
